Antonov designated a variant with a modified electrical system and an additional augmented flight control system the An-22A but the designation was not used by the military. Those aircraft had the radar mounted below the right wheel well fairing, forward of the wheels. Prototypes, such as the one first featured at the 1965 Paris Air Show had fully glazed noses that lacked the nose-mounted radar of production models. Only one production variant was built, the standard An-22. Soviet 1965 post stamp showcasing the An-22 success at the Paris Air Show. Also of note are large anti-flutter masses on the top of each tail. This gives the An-22 better engine-out performance, and reduces height restrictions for hangars. The An-22 has the general appearance of an enlarged version of the earlier Antonov An-12 except that it is fitted with a twin tail. The An-22 has set a number of payload and payload-to-height world records. Like the An-12, the aircraft has a circular fuselage section. This allows the rear cargo doors to be opened during flight for paratroops and equipment drop. A door equipped with pressure bulkhead is located at frame 14, separating the cargo attendant's compartment from the main cargo compartment. The forward fuselage is fully pressurized and provides space for 5 to 8 crew and up to 28 passengers, but the cargo space is pressurized to only 3.55 PSI / 0.245 bar allowing for a lighter airframe. ![]() The An-22 follows traditional cargo transport design with a high-mounted wing allowing a large cargo space of 33 m in length and a usable volume of 639 m³. That feature was removed in later models. ![]() In early versions tire pressures could be adjusted in flight for optimum landing performance. The landing gear is ruggedized for rough airstrips. The propellers and exhaust from the engines produce a slipstream over the wings and large double-slotted flaps. This is achieved by four pairs of contra-rotating propellers, similar to those on the Tupolev Tu-114. It has the capability to takeoff from austere, unpaved, and short airstrips, allowing airborne troops to perform air-landing operations. The An-22 cargo hold can accommodate four BMD-1s compared to only one in the An-12. ![]() The aircraft was designed as a strategic airlifter, designed specifically to expand the Soviet Airborne Forces' capability to land with their then-new BMD-1 armoured vehicles. All aircraft were built at the Tashkent State Aircraft Factory and the first military delivery was made to the Air Transport Wing at Ivanovo Airbase in 1969. ![]() The prototype was given the name Antaeus (sometimes misspelled Antheus) and, after four-months of test flying, was displayed at the 1965 Paris Air Show. The prototype, now designated the An-22, was rolled out on 18 August 1964 and first flew on 27 February 1965. In the early 1960s, the Antonov bureau produced a wooden mock up at its Kyiv, Ukraine, workshops of what was designated the Model 100. Originally known as the An-20, the model is a conventional multi-engined high-wing design. In the late 1950s, the Soviet Union required a large military transport aircraft to supplement the Antonov An-8 and An-12s then entering service. Thereafter, the model saw extensive use in major military and humanitarian airlifts for the Soviet Union, and is still in service with the Russian Aerospace Forces.ĭesign and development First prototype of the An-22, pictured in 1991 at Gostomel Airport. The An-22 first appeared publicly outside the Soviet Union at the 1965 Paris Air Show. Powered by four turboprop engines each driving a pair of contra-rotating propellers, the design was the first wide-body transport aircraft and remains the world's largest turboprop-powered aircraft to date. The Antonov An-22 "Antei" ( Russian: Ан-22 Антей, An-22 Antej English Antaeus) (NATO reporting name " Cock") is a heavy military transport aircraft designed by the Antonov Design Bureau in the Soviet Union.
